Captain America and Black Widow

Cullen Bunn and Francesco Francavilla teamed for this five-issue Marvel series from 2012–2013, pairing Earth's Mightiest Heroes in a tense, globe-trotting thriller. Francavilla's moody, noir-infused artwork perfectly complements Bunn's script, which pits the duo against a shadowy conspiracy that tests their trust and combat skills. A focused, self-contained story, it showcases the dynamic between Steve Rogers and Natasha Romanoff without the baggage of a larger event.
